[QUOTE="Nomosendero, post: 457681, member: 3622"] Nothing wrong with 223AI & I may still do that. The 223 case cap. is more than the 222, but less than the 222 mag, most manuals have loads for a 222 Rem, but in the newer manual I have only my new Speer manual had loads for the 222 Rem Mag. Here is what Speer says about the 222Mag & Cartridges of the World say the same basic thing: "Case capacity is 20% greater than the 222 Remington & about 5% greater than the 223." But the older 222 Magnum version was loaded to lower pressures, as was the case with several older rounds. Here is what the Nosler Manual says about the 204 case; "The 204 was developed from the 222 Remington Magnum, which has the LARGEST CASE CAPACITY in the 222 family". Bottom line is the 222Magnum was the biggest case of the 222 family, due to case length. Plus when Ruger/Hornady chose the slightly bigger 222 R. Mag case, the "blew it out" /took the taper out, so now a wee bit more than 5% & will be of course a bit more than 223AI. NOTE: The 223 info in 6mmbr does give about a 7-8% increas in cap, therfore it appears that the 204 case is not maximized the same extent as the 223AI was, so an AI version of that would have to be fireformed too, so no gain there in steps involved, but it is a bigger case, so you would have to end up with more.
